This is the standard, round, full-size, one-piece valve that has been used successfully in columns around the world for over 50 years.
- It is provided in several leg lengths to accommodate various tray deck thicknesses.
- It is normally dimpled to help prevent sticking to the deck, but can be flush seated if needed.
- The orifice can be made to prevent the valve from spinning.
- Dual valve weights may be used in alternating rows to extend the already wide operating range.
